In 1964, Dolan strategically partnered with the city of New York to lay the groundwork for wired cable in several Manhattan buildings. He soon expanded his offerings, securing a deal to broadcast Knicks and Rangers playoff games on cable to enhance viewer interest, as reported by Variety. Dolan's legacy includes establishing Home Box Office (HBO), elevating movie broadcasts on cable, and subsequently creating Cablevision, which provided television and internet services across the northeastern U.S.

The Dolan family's media influence reached a peak in 2015 when they sold Cablevision to the European firm Altice for approximately $18 billion. At that time, his son James was overseeing the family's operations, which had garnered both admiration and criticism as fans expressed frustration over the Knicks' performance and contentious programming decisions that threatened popular events like the Academy Awards.

At the time of his death, Dolan's net worth was estimated at $5.4 billion, according to Forbes. His impact on the cable television landscape remains undeniable, as he shaped the viewing habits of millions across the region.
